Affected and other Assembly Bodies

The risk and the related corrective action required are relevant only for HI-FOG

1900 sprinklers (see Chapter 2 to identify) when installed in some A1000 types

Assembly Body, which contain an internal stop valve.

HI-FOG sprinkler installed in other types of Assembly Body require none of the

actions referred to by this document.

To differentiate the A1000 Assembly Body from other Assembly Body types note

the following:

With the A1000 type Assembly body there is no gap between the HI-FOG

1900 sprinkler and the cover plate when the HI-FOG 1900 sprinkler is

installed (see Figure 01). The cover plate (see Figure 01) of A1000

Assembly body types is held in place by the sprinkler.

The A2000 Assembly body type is suitable only for HI-FOG 2000 sprinklers

(see Figure 02 for sprinkler types).

A HI-FOG 1900 sprinkler installed in an AB type Assembly body would either

leave a 2 – 3 mm gap between the top of the sprinkler and the cover plate,

or would have an adaptor ring filling the gap.

See Figure 03 for AB types below – left half without adaptor ring and right

half with adaptor ring. The cover plate of AB type is connected to the

Mounting Adaptor with a lock ring.

The C type the installation with HI-FOG 1900 sprinkler would leave a narrow

gap between the top of the sprinkler and the cover plate - The cover plate of

C type is snapped directly to the Assembly body.
